3/4in NPT ML - 1/4in NPT FM Reducer Blue

The 3/4in NPT ML - 1/4in NPT FM Reducer Blue from REDHORSE PERFORMANCE is a precision aluminum bushing fitting engineered for custom fuel, coolant, and hydraulic systems in high-performance vehicles. This straight reducer bridges two different port sizes, allowing mechanics and enthusiasts to adapt larger diameter lines to smaller diameter components without compromising flow or system integrity. Built for applications where space constraints or component compatibility demand a compact transition, this fitting serves as a critical adapter in turbo kits, fuel rails, cooling upgrades, and custom plumbing configurations.

Machined from aluminum and finished in vibrant blue anodizing, the 912 Series reducer delivers both corrosion resistance and visual distinction in engine bays. The 3/4-inch NPT male threads accept larger hose connections or male-threaded ports, while the 1/4-inch NPT female outlet allows installation of smaller-diameter hardline or soft hose components. NPT (National Pipe Tapered) threads create a mechanical seal without requiring additional sealant tape or paste, though most builders apply PTFE tape as standard practice for reliability in high-vibration automotive environments. The straight design eliminates flow turbulence compared to elbow adapters, making it ideal for fuel distribution blocks, coolant manifolds, and pressure-fed systems requiring minimal restriction.

Street machine builders, drag racers, and LS swap specialists rely on REDHORSE fittings for custom fuel system layouts where OEM ports don't align with aftermarket fuel rails or surge tanks. The compact 2.835 × 1.405 × 4.423-inch profile fits tight engine compartments common in vintage restorations and modern platform swaps. Installation requires only a wrench and basic thread-sealing compound; threaded connections remain accessible for future modifications or system flush procedures. Whether you're retrofitting a carbureted classic with EFI, upgrading a turbo system's coolant lines, or fabricating a custom fuel cell installation, this REDHORSE reducer ensures proper flow adaptation across mismatched port sizes.
